To all whom it may concern. 7

Be it known that I, S'rnvn SrARonvIoH, a citizen of the United States, residing at Ronald, in the county of Kittitas and State of \Vashington, have invented certain new and useful Improvements in Miners Safety- Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvementsin miners lamps of the safety type and has for complished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims.

WVith reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure l is a side elevation being partly in section showing my improved lamp attachment inposition, Fig. 2

is a detail perspective view of the upper reflector showing it attached to the chimney which is shown in section, Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1, Fig. 4C is an enlarged detail fragmentary vertical sectional view showing the lock for the wick tube in position, and Fig. 5 is a detail perspective view of the spring lock for locking the wick tube in position.

Referring to the drawings by characters of reference, A designates as an entirety a well known type of lamp which consists of a body B which includes a base 1 upon which is mounted a preferably cylindrical shell 2. Mounted within the shell 2 is the oil container 3.

The upper side of the body B is open and has formed about the open side an upstandmg exteriorly screw threaded annular flange 4. Turned upon the screw threaded flange 4; is a ring 5 which supports upstanding guard rods, 6. The guard rods 6 are connected to a suitable plate 7 carried upon the lower edge of a safety ventilator designated 8 as an entirety. The safety ventilator 8 is of well known construction. A hook 9 is carried upon the upper end of the ventilator 8 to provide for the attaching of the lamp in the desired place. A glass cylindrical chimney 10 is secured at its lower edge within the opening in the body B and to the'flange 4 so as to communicate with said shell 2. The upper edge of the chimney 10 terminates at a point spaced from the plate 7.

My invention consists of a reflector and chimney engaging the metallic plate 11 that is mounted upon the upper end of the chimney 10 and is formed with a central opening 12. A suitable gasket 11 is interposed between the plate and chimney. Theplate 11 is arranged to communicate by means of the opening 12 with the ventilator 8 and is of circular shape andhas its periphery.disposed flush with the outer face of the chimney l0.

Carried upon the inner face of the plate 11 is a concavo-convex reflector 13, formed with a central circular opening which alines with the opening 12 in the plate 11. This reflector 13 is disposed with its concavcd face downmost and is of less diameter than the chimney 10 in which it is disposed. The lower edge of the reflector 13 engages the inner face of the chimney 10.

Disposed within the lower end of the chimney 10 is a concavo-convex reflector 15 disposed with its concaved face uppermost. This reflector 15 is secured within the lower end of the chimney 10 after the same manner as the reflector 13. The lower reflector 15 is provided with a central opening through which is inserted a wick tubereceiving tube 16. The tube 16 is soldered or otherwise suitably secured intermediate its ends to the reflector 15 and so as to extend to a point above the center of the reflector and terminates in a plane with the upper edge thereof. The tube 16 is extended into the oil reservoir or container 3 and has mounted therein a wick tube 17 arranged to be moved into and out of position within said tube 16. A wick 18 is mounted withinl,

the'wick tube 17. The wicktube 17 isprovided upon its upper edge with a laterally projecting flange 19.

n approximately V-shaped spring 20 arranged between the wick and wick tube receiving tube 16 and 17 on one side thereof,

one arm portion of the spring 20 is disposed I has its inner end disposed to engage the, outer or other arm portion of the spring.

The other arm portion of the spring 20 engages the wick tube 17 and at its upper end vis designed to engage the under face of the flange 19. By turning the screw 21, the outer arm 22 of the spring 20 is forcedinto supporting engagement underneath the flange 19.

With reference 'to the foregoing description it will be seen that a lamp including the body B, chimney 10 and ventilator 8 may be readilyequipped with the attachment, namely, the reflectors and wick tubes without requiring any material change in theconstruction of the lamp. The lowerreflector 15 is arranged with an arcuately arranged series of ventilatin openings 23 on one side of the tube 16." of the reflector 15 an elongated opening 24 is'formed so that suitable igniting "means, not shown, may be placed in position to ignite the wick.

With reference to the foregoing description and accompanying drawings it will be observed that I have provided an attachment for miners lamps, which is capable of being readily attached and will increase the'lighting efliciency of a lamp.

In practice, I have found that the form of my invention, illustrated in .the drawings and referred'to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing'that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportionand arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as set forth.

What is claimed is 1. The combination with a minerslamp consisting of a base, an oil container in said base, a ventilator and transparent chimney 6n the other side interposed between the ventilator and base,

vof an attachment comprising a plate mounted upon the edge of said chimney and having a central opening therein communicating with the ventilator, a concavo-convex reflector. secured upon the under face of the plate and having an opening therein alining with'the opening in said plate, and a concavo-convex reflector mounted within the lower part of the chimney and partially disposed within the base and having ventilating openings therein, a central guide tube positioned through the reflector and secured to the base, its upper edge terminating flush with the edges of the reflector, a wick tube slidably mounted in the guide tube and disposed within the oil container of the base, its upper end provided with an out turned flange, means secured between the wick tube, and the guide tube engaging the out turned flange of the wick tube for holding the same inbposition, a wick mounted in said wick tu e.

2. The combination with a miners lamp consisting of a base, a ventilator and transparent chimney interposed between the ventilator and base, and an attachment comprisinga plate mounted upon the upper edges of the chimney and provided with a central opening communicating with the ventilator, a concavo-convex reflector having an opening centrally thereof secured to the walls of the opening of the plate and to the under base thereof, and a concavo-convex reflector mounted in the lower part of the chimney and partially within the base provided with a centralop'ening therein, a guide tube secured in the base and extending up through the opening in the reflector the upper end terminating flush with the edges of the reflector, a wick tube slidably mounted in the guide tube, a wick carried by said tube, a substantially V shaped spring located between the guide tube and wick tube, means extending through the guide tube and extending through one arm of the V shaped spring and engaged against the inner face of the adjacent arm for forcing the same into frictional engagement with the wick tube for holding the same in position therein.

In testimony whereof I aflix my signature in presence of two witnesses.
